JOININGOR CONNECTING RAILROAD-RAILS;

SPECIFICATION forming part of Letters Batent No. 730,928, dated June 16, 1903.

Application filed January 2, 1903.

To all whom it may-concern.-

Be it known that we, JOSEPH F. KOEI-ILER and JOSEPH F. MILDE, citizens of the United States, residing at Jackson, in the county of Cape Girardeau and State of Missouri, have invented a new and useful Method of Joining or Connecting Railroad-Rails, of which the following is a specification.

Our invention consists of an improved method of joining or connecting railroadrails so as to form practically a continuous rai Figure 1 is a side elevation of the jointed ends of two rails with fish-plate attached. Fig. 2 is a cross-section on line 2 2, Fig. 1. Fig. 3 is a broken side elevation of the abutting or jointed ends of two rails, clamp-bolts shown in section. Fig. 4 is a perspective view of the tenoned end of a rail; Fig. 5 is a perspective view of the mortised end of a rail.

The rails to which this joint applies are common T-rails. One end of each rail is supplied with a tenon and the other end with a mortise. The tenon is formed bycutting away the head or tread and part of the flange of a rail, leaving a perpendicular face 4 extending at the upper part about half-way down the web. The top of the web is cut horizontally, as at 1, leaving the tenon to consist of the lower portion of the web, and a head :2, which is composed of thweb and a part of the flange. The neck of the tenon behind this flange consists of the bottom portion of the web only. It will be seen that the parts removed from the rail are all cut away on horizontal or perpendicular lines and there are no beveled surfaces. The

' mortised end of each rail is formed by cutting ment of the rails.

Serial No. 137.590. -(N0 model.)

11,behind the projecting ends 8 8, forms a receptacle for the head 2 of the tenon.

In coupling the joint the rail with the tenon thereon is first placed in position. Then the mortise of the next rail isplaced directly over the tenon and this rail is lowered to place.

The mortise and tenon then form a lock against either lateral or longitudinal move- The fish-plates 9 embrace the web and flange of the rail, as is common, and are secured in place by bolts 10, passing through the web and plates, as .is common. hen the fish-plates are'applied; the mortise rail is held down, and hence the joint is locked in all directions. As all abutting surfaces are perpendicular, there is no wedging action of the parts to spread or dislocate them, as issometimes the case with scarfed or beveled rail-joints.

\Vhat ,we claim is 1. In a railjoint, the combination of a tenoned T-rail having a portion of the head and flange cut away in perpendicular direction, and the upper portion of the web cut away in horizontal direction, and a mortised rail having the full thickness of the lower part of the web correspondingly removed,

and having a rectangular socket between retained portions of the flange.

2. The combination with a tenoned rail having the lower part of the web intact, and having a head consisting of the inner parts of the flange and a narrow neck behind the same of the width of the web only, of a mortised rail having the lower part of the Web removed between projecting portions of the flange,v

and having a cup or socket to receive the tenon-head, substantially as described.

In testimony whereof We have signed our names .to'thisspecification in the presence of two subscribing witnesses.
